Venting – direct exhaust – vertical or sidewall
1. Do not mix types or manufacturers of vent materials.
. Clean all joints before sealing. See vent manufacturer's instructions
for cleaning and sealing joints. Use their specified sealant. Do not use
screws.
3. Install vent pipe with seams on top of vent horizontal runs. Follow
requirements in Section 3e, page 17, for vent termination.
4. Maintain minimum " clearance from combustible materials to vent
pipe.
Vertical venting
5. — See Figure 13. Follow vent manufacturer's instruc-
tions for venting through roof.
• Vent pipe must extend through roof flashing, jacket or thimble.
• Vent may pass through floor, inside wall or concealed space when
installed according to vent manufacturer's instructions.
Sidewall venting
— See Figures 14 and 15. Vent must terminate
at least one foot above anticipated snowline. Vent must be termi-
nated only with:
• Tee or elbow with integral screen. Tee must be mounted vertically.
• Elbow and termination coupling with screen (not available for
StaR-34).
6. Do not seal vent pipe (slip connector for Saf-T Vent) to inside or outside
plate.
7. If passing through noncombustible wall, provide hole diameter large
enough to insert the vent pipe (slip connector for Saf-T Vent).
8. Install horizontal drain tee as close as possible to boiler, in first horizontal
run. See Figure 13.
9. Do not exceed the maximum vent system length given in Table 4,
page 15.
Condensate drain line — use only silicone tubing
rated for at least 400°F for the condensate drain line.
Using any other material could cause flue gas leakage,
potentially resulting in severe personal injury, death
or substantial property damage.
On some installations, the condensate drain fitting
may be omitted, provided:
• Vent manufacturer shows this option in their
instructions.
• Vent is sloped toward termination as shown in
dotted lines in Figure 14.
• The vent is installed per Weil-McLain and vent
manufacturer's instructions.
Condensate drippage from such vents may accumu-
late on the ground below. Consider traffic in the area
to avoid hazard due to ice accumulation. Ice buildup
may also block vent.
